Problem with array ???

habbardone

Hi,
I have written a little script that uses a form with several lines that are generated with an array - but for some reason the array elements are not getting stored !

Can someone tell me what I am doing wrong ! Thanks
David.

<?php
if(isset($_POST['sal_fm'])) 
{  

   for($i = 1; $i < 6; $i++ )
    {
       echo "$_POST{so_dat[$i]} $_POST{so_num[$i]} ";
       }  // end for loop
  }  //  END  IF

else
{		 			
?>
<div style='position:absolute;left:100px; top:100px;' >
<form  action ='a_test3.php'method = 'POST'>
<input type='hidden' name='sal_fm' value='yes' />
<table style='width:400px; table-layout:fixed;' border = '1' cellspacing = '2' >

<?php
$today = date(U);
for( $i = 1; $i < 6; $i++ )
  {
  if($i == 1)
	 { 
	 $so_dat_def[$i] = date('d-m-Y',$today);
	 } 
	else
	 {
	 $so_dat_def[$i] = 'same';
	 }

?>

<tr>
<td><input type='TEXT' name='so_dat[$i]' value="<?php echo (isset($_POST[sal_fm]) ? $_POST['so_dat{$i}'] : $so_dat_def[$i] ); ?>" 
size = '20' maxlength='140'/></td>

<td><input type='TEXT' name='so_num[$i]' value="<?php echo (isset($_POST[sal_fm]) ? $_POST['so_num{$i}'] : '' ); ?>" 
size = '20' maxlength='140'/></td>

</tr>

<?php
 } // end for loop

?>


<tr>
<td ><input type='submit' class='btn_long' name = 'batch' value = 'Next Order' 
onMouseover="this.style.backgroundColor='red'" 
onMouseout="this.style.backgroundColor='yellow'" ></td>
</tr>

</table>
</form>
</div>

<?php
 } // end else
?>

The result I get from rinning this and filling in the form is this :

Array{so_dat[1]} Array{so_num[1]}
Array{so_dat[2]} Array{so_num[2]}
Array{so_dat[3]} Array{so_num[3]}
Array{so_dat[4]} Array{so_num[4]}
Array{so_dat[5]} Array{so_num[5]}

Thankss

Hi there.

A couple of things:
- For debugging turn all error reporting on (including notices). This shows that you sometimes use constants instead of strings (like in date(U) instead of date("U"); )
- use var_dump on $POST to see what's really coming to your script
- to tell PHP that there is an array in $POST, use name[] as name. Indexes will be added automatically.

<?php
if(isset($_POST['sal_fm']))
{
   var_dump($_POST);
   echo "<br>You can use var_dump to see what's really comming to your script.
   Disable it after debuging <br><br>";
   $so_dat = $_POST['so_dat'];
   $so_num = $_POST['so_num'];
   for($i = 0; $i < count($so_dat); $i++ )
    {
       echo $so_dat[$i]." - ".$so_num[$i]."<br>";
       }  // end for loop
  }  //  END  IF

else
{
?>
<div style='position:absolute;left:100px; top:100px;' >
<form  action ='test1.php' method = 'POST'>
<input type='hidden' name='sal_fm' value='yes' />
<table style='width:400px; table-layout:fixed;' border = '1' cellspacing = '2' >

<?php
$today = date("U");
for( $i = 1; $i < 6; $i++ )
  {
  if($i == 1)
     {
     $so_dat_def[$i] = date('d-m-Y',$today);
     }
    else
     {
     $so_dat_def[$i] = 'same';
     }

?>

<tr>
<td><input type='TEXT' name='so_dat[]' value="<?php echo (isset($_POST['sal_fm']) ? $_POST['so_dat{$i}'] : $so_dat_def[$i] ); ?>"
size = '20' maxlength='140'/></td>

<td><input type='TEXT' name='so_num[]' value="<?php echo (isset($_POST['sal_fm']) ? $_POST['so_num{$i}'] : '' ); ?>"
size = '20' maxlength='140'/></td>

</tr>

<?php
 } // end for loop

?>


<tr>
<td ><input type='submit' class='btn_long' name = 'batch' value = 'Next Order'
onMouseover="this.style.backgroundColor='red'"
onMouseout="this.style.backgroundColor='yellow'" ></td>
</tr>

</table>
</form>
</div>

<?php
 } // end else
?>

A BIG thank you - that really helped.

just one thing - I still have a problem with
this:

I am using the following code to capture 15 lines of data.
The problem is if the selected variable contains a space eg "Joe Customer" then I only
get the first part ( ie Joe ) stored in my array.

Why is this and how do i get the whole string stored ?

Thanks for any help.

for($i=0;$i<15;$i++){
<tr><td>
   <select name='acc_nam[]'>
   <?php 
    $sql = "SELECT account_name FROM $client_table
		 	 WHERE account_type ='CUS'  ORDER BY 'account_name'";	

$result = mysql_query($sql)
   or die("Couldn't execute FIRST query.");	

while($row = mysql_fetch_array($result)) {

      if ($acc_nam[$i] == $row[account_name]){
 echo "
 <option value = {$row[account_name]} selected= \"selected\" >$row[account_name]</option>";
 }    // endif
      else {
echo "<option value = {$row[account_name]}>$row[account_name]</option>";
 }   // end else
      }     // end while loop			 
?>
</select></td></tr>
 }     // end for loop

Put the value in quotes instead of brackets:

 
echo "<option value=\"$row[account_name]\"  selected>$row[account_name]</option>";
